[LLVMdev] gcc 4.1* carashes compiling llvm-gcc

The version of binutils is 2.17

By the way. I will use the opportunity to ask you again :) I tried to
compile with gcc 4.0.4. It successfully compile LLVM but fails
compiling LLVM's gcc front end. The problem is architectural 32 and 64
bit. The machine has intel xeon CPU that is physically 32 bit but has
64 extension x86_64 (or something like that, I am not exactly sure).
The error message that I get is bellow. I noticed also that the
compilation command specifies "-m32" flag which probably shouldn't be
passed.
